Super-efficient Source Four LED tungsten luminaire creates stunning warm-spectrum white light with a 3000K color temperature. The high-light-volume, low-energy fixtures replicate the light of conventional tungsten sources while requiring less power to run. Source Four LED tungsten fixtures can be a stand-in for or used alongside tungsten units for large quantities of rich, warm white light. Source Four LED luminaires are the same size as a traditional Source Four, so can use them on a regular light rig without worrying about taking up too much space. Even at their compact size, they are incredibly efficient, with a better lumens-per-watt ratio than other, larger LED spots. And with a 50000 hours lamp, won’t spend time swapping out bulbs. Intelligence comes standard. Drawing on ETC’s industry-leading experience with control systems, Source Four LEDs are outfitted with a user interface with convenient settings and modes to simplify work and customize fixture performance. Source Four LED luminaires use the same barrel, accessories and lenses as traditional Source Four fixtures. Adding an ETC Source Four EDLT (Enhanced Definition Lens Tube) to a Source Four LED makes the beam even crisper for the best possible performance. All of the same EDLT lens options are available for the Source Four LED, along with an LED-only 50° tube.
